1. The problem statement, all variables and given/known data See the image attached 2. Relevant equations Ex = (Kλ/R)*∫3/2ππ/2(cosθ)dθ 3. The attempt at a solution Ey cancels because there is an equal amount of force in both y directions. For the electric field on the x axis, the above equation can be used. Given that λ=Q/L λ=(85x10^-9 C)/(0.1 m) =8.5x10^-7 R = L/θ =(0.1 m)/(3/2π - π/2) =0.03183 E = ((8.85x10^-9)(8.5x10^-7)/0.03183)*pi = 7.424640507894822×10^-13 This is not correct. Please help! Thanks in advance.
